IQ vs Shoe Size - Outlier: As mentioned earlier in this chapter, outliers can make a correlation when one doesn't really exist. Here is the example of clown's shoe sizes versus IQ. Below is a list of the data from 10 different clowns. The last entry is for Bozo the clown who was unusually intelligent and wore very large shoes. r = Shoe Size 9 8 10 11 7.5 9.5 9 10.5 10 18 y = IQ 95 85 110 85 115 95 107 102 90 155 (a)" Create a scatter plot from this data. Do one scatter-plot of all the data and one scatter plot which excludes Bozo. Include the regression line and the regression equation on the graphs. (b) What happens to the regression line when Bozo is excluded? (c) What is the correlation coefficient including Bozo? Is there a significant linear correlation? (d) What is the correlation coefficient if you exclude Bozo? Is there a significant linear correlation? (e) Summarize what Bozo did to the correlation between shoe size and
